# Ultrasonic cleaning of skate bearings and parts

Ultrasonic cleaning of skate bearings and parts is a Bogdanca service: ultrasound flushes old grease, sand and dust out of the bearing, with no mechanical interference with its components. Washing, rinsing and drying with compressed air usually takes 20–30 minutes. On request we lubricate the bearings with oil or grease. You bring the parts to the shop or send them by post.

## Who it’s for

- Your bearings, after skating in the rain, on sand or in a skatepark, hum and spin only briefly.
- You skate regularly and want to refresh your bearings every 2–3 months instead of buying new ones.
- You have aluminium frames, axles or spacers caked in old grease and want them thoroughly cleaned.
- You live far from Poznań and Wrocław — you send the parts by post and get them back after the service.

## When to choose something else

- Your bearings have noticeable play or signs of corrosion on the raceways — washing won't undo that, and you will need new [bearings](https://bogdanca.pl/en/wheels-and-bearings/bearings).
- You prefer to wash bearings yourself — see the [Sonic Sports Turbo Wash Bio cleaner](https://bogdanca.pl/en/sonic-sports-turbo-wash-bio-bearing-cleaner.html).

## Key features

- **Cavitation instead of a brush** — Ultrasound creates microscopic bubbles in the liquid, which reach the gaps inside the bearing — where neither a cloth nor a brush can.
- **Washing without mechanical interference** — Dirt and grease residue come off without pressure on the rolling elements and without affecting the bearing's internal clearance, which cannot be said of scrubbing by hand.
- **Large service-grade cleaner** — It takes whole sets of parts, including aluminium frames, so we clean the frame as a whole, not piece by piece.
- **Rinsing and drying with compressed air** — The parts come back to you dry, with no liquid left in the crevices.
- **Lubrication on request** — After washing we apply fresh oil or grease chosen for your riding style — say so when placing your order.
- **Postal service** — After you add the service to the basket, you get a ready shipping label by email; you print it, stick it on the parcel and send it from a Paczkomat.

## Questions and answers

### Is ultrasonic washing safe for bearings?

Yes. The waves remove dirt and old grease without interfering with the rolling elements or the bearing's internal clearance, so it is a gentler method than washing by hand.

### How long does cleaning take?

Usually 20–30 minutes: washing, rinsing and drying with compressed air. With the postal service, the whole process, from sending the parcel to receiving the finished parts, usually takes 3–5 working days.

### Can I send my bearings instead of coming to the shop?

Yes. You add the service to the basket, get a ready shipping label by email and send the parcel from a Paczkomat; transport in both directions is charged extra. It goes fastest if you send the parcel in the morning.

### Are the bearings lubricated after washing?

Yes, if you ask. We apply oil or grease chosen for your riding style — say so when placing your order.

### What else besides bearings can I hand in for cleaning?

Spacers, axles, bolts, aluminium frames and other small metal parts, as well as jewellery or precision tools.
